motor, alarm tests are completed,
|
|
||||||
|
|
||||||
functionalities work perfectly without errors
|
|
||||||
|
|
||||||
expected objectives achieved: by changing real-time signals on Firebase, the embedded system can be controlled properly
|
|
||||||
;turn on/off motor/alarm
|
|
||||||
|
|
||||||
physical button tests are planned to be completed soon......
